the picture in which spawned this story can be found here:
A follow-up to ~EbonMane's In the Rain, following the Silence ending.
One night I had a disturbing idea, why not make a story where Pinkie goes inside Rainbow?
So, with the help with my extremly messed up mind I thought out this story.
It's pretty much rough with a few typo's because I typed this in note pad, and the fact that half of it contains whatever I thought of as I was typing doesn't help.
I could have spent more effort on a less comedic ending though
